1) Paper preview: Precision Measurement of the Longitudinal Double-Spin Asymmetries for Dijet Production at Intermediate Pseudorapidity in Polarized $pp$ Collisions at $\sqrt{s}$ = 200 GeV

- Brief introduction from the PWG conveners (5’) [Qinghua Xu]

- Paper proposal (15') [Presentation by Ting Lin]

- Open discussions (35')

- Summary from the conveners' panel (5’)

Proposal page: https://drupal.star.bnl.gov/STAR/blog/tinglin/Paper-Proposal-2015-pp200-Endcap-Dijet-ALL-Measurement

PA: Ting Lin
Target journal: PRD

NOTES

2) Data production

Production priority (LIST)
- Treat O+O data with two polarities as two independent datasets in terms of calibration
Embedding - Run19 19.6 GeV TpcRS tuning (SLIDES)
- nTimeBucket comparison, difference seen in data/MC, particularly for low pT tracks. Impact on efficiency is very small
- nHits comparison looks reasonable. Some further tuning was done.
- Mostly ready to produce embedding samples for BES-II data.
eTOF calibration
- 7.7 GeV almost ready
- 9.2/11.5 still running
- Run20 FXT: clock jump issue largely improved. now overall 0.1% remaining contribution, two counters have <5%. Currently investigating the multiplicity dependence.
BES-I MuDst->PicoDst conversion
- AuAu62_production, P10ik
- AuAu39_production P10ik
- AuAu27_production_2011 P11id
- AuAu19_production P11id
- AuAu11_production P10ih
- AuAu7_production P10ih
- Chain option: picoDst PicoVtxMode:PicoVtxDefault PicoCovMtxMode:PicoCovMtxWrite PicoBEmcSmdMode:PicoBEmcSmdWrite
Run17 st_fms: new production with P22ib done
- Can we remove MuDst and PicoDst of P18ic?
BES-II datasets are being duplicated (Progress)

Conclusions:
- Conveners agree with the current priority of producing 200 GeV d+Au and O+O data before other Run21 datasets given that quite a few groups are interested in analyzing these data for QM.
- Run20 FXT data: the eTOF software coordinator is currently investigating the multiplicity dependence of the impact of the clock jump. Once done, we will summarize all the findings and caveats, and communicate with analyzers.

- Run17 st_fms P18ic data can be removed from distributed disk

Conclusions
- Conveners are supportive of the proposal to switch the priority between Run21 d+Au and O+O
- No feedback received for the chain option to be used for converting BES-I MuDst files to PicoDst. Will propagate this to the production team.

2) Hot QCD Community White Paper

From Megan: "Jean-Francois and I were asked to organize a Hot QCD white paper that helps put the other white papers in context of the physics goals in our field. My understanding is that STAR was preparing to write a white paper but wanted to suggest that we join efforts and would like to invite those in STAR who were planning to contribute, to help write the relevant sections of the document we are preparing. Below is the draft outline of topics that we are planning to cover. We appreciate any recommendations you have for writers or any other suggestions on this process."
STAR members already in the committee: Xin Dong, Prithwish Tribedy, Jiangyong Jia, Kong Tu

Conclusions
- We will not write a separate STAR white paper. But instead, use the BUR as the reference for details.
- Will propose the following people to join the hot QCD community white paper writing committee: Rongrong Ma, Takafumi Niida, Dan Cebra, Nihar Sahoo

3) Data production news

DAQ proudction
- Run17 pp 510 GeV st_fms with pp2pp option - done (0.5% remaining)
PicoDst -> MuDst conversion
- Run17 pp 510 GeV st_physics - done
  - Is the jet tree production finished? Can we remove MuDst files from RCF?
- Run12 UU 193 GeV - done
- Run14 AuAu 200 GeV prod_low/mid - waiting for PWG QA to resume
Data restoration
- Run16 st_upc MuDst - done
- Run11 AuAu 200 GeV - done (DD+RCF)
- Run18 FXT AuAu 3 GeV - duplicated on DD
Anyone using MuDst of pp500_production_2013 P14ia and P14ig data? We have 2% - 60% on DD depending no the data stream.

Conclusions
- Run17 pp 510 GeV st_physics: need a couple more weeks to produce jet tree from MuDst.
- pp500_production_2013: ColdQCD PWG will check if anyone is using MuDst files of this dataset

4) Data production priority (PRIORITY LIST)

Run21: O+O vs. d+Au
Run22: st_physics, st_mtd, st_fwd, st_W

Conclusions

- FCV PWG prefers to have a slightly higher priority for O+O than for d+Au. Looking forward towards QM 2023, if we want to show results from O+O, we probably need to produce them immediately after 11.5 GeV Au+Au data. Will continue to discuss this.
- Run22 datasets will be produced after Run21 datasets. For the four main streams in Run22, st_mtd can be placed with lowest priority. ColdQCD PWG will discuss the relative priorities of the other three data streams.

1) Paper preview: Strangeness Production in 3 GeV Au+Au Collisions at RHIC

- Brief introduction from the PWG conveners (5’) [Dan Cebra]

- Paper proposal (15') [Presentation by Yingjie Zhou]

- Open discussions (35')

- Summary from the conveners' panel (5’)

Proposal page: https://www.star.bnl.gov/protected/heavy/yjzhou19/strangeness/paper/

PA: Xin Dong, Yue-Hang Leung, Yaping Wang, Guannan Xie, Nu Xu, Yingjie Zhou
Target journal: PLB

2) Organizational news for LFSUPC co-convener

Incoming: Yue Hang Leung
Outgoing: Dan Cebra

3) New PWGC meeting time: 9am BNL time on Fridays?

Conclusions: will change the meeting start time from next week (Nov. 18th)

4) Data production priority (PRIORITY LIST)

Run21: O+O vs. d+Au
- Production time: 2 weeks each
- Calibration time: d+Au - 4 weeks; O+O - a few months
Run22: st_physics, st_mtd, st_fwd, st_W, st_upc, st_zerobias

Conclusions:
- One suggestion: (Run20+21) 26.5 FXT (7.2) > 3.85 FXT I (3.0) > 44.5 FXT (9.2) > 70 FXT (11.5) > 100 FXT (13.7) > 200 GeV d+Au > 200 GeV O+O >? 17.3 COL > 3.85 FXT II (3.0). Will continue the discussion next week.

- PWGs are asked to poll the interests of analyzing O+O data for QM
- Suggested Run 22 priority: st_upc > st_zerobias > st_W > st_physics > st_fwd > st_mtd
-- ColdQCD PWG will determine a list of runs for EMC calibration, which could be produced before physics production
-- it should be very fast to produce st_upc and st_zerobias streams
-- need to discuss with S&C team whether it is efficient to produce st_zerobias stream standalone and couple it with other data streams

5) Embedding production

Mismatch seen in nHits distributions was identified to be offline vs. online cluster finder, which is now fixed for Run18 and BES-II. (See DETAILS here)
Need 1-2 weeks to fine tune TpcRS after fixing the cluster finder issue
Do we need to prioritize the embedding requests or just follow the natural order according to the request date (first come first serve)?
FXT embedding strategy

Conclusions:
- Currently, we can go with the natural order of embedding requests, i.e. first come, first serve
- Will discuss priority for embedding production needed for HP2023 conference
- Dan presented and submitted some FXT embedding request with high priority in order to verify if it is OK to combine embedding production for various FXT energies

6) Agenda for Dec. analysis meeting: DRAFT

Conclusions: will continue the discussion next week

2) Centrality meeting on Oct. 18th, 11am BNL time

Centrality for low-energy collisions (other than two-component Glauber approach) - Dan Cebra
Zoom: https://bnl.zoomgov.com/j/1605112744?pwd=RTJFMzQzM0tTZ3padml4VEEvbzUrdz09

AOB
- What is the definition of small-sized dataset that could be duplicated on DD?
- At this point, we suggest that PWGs ignore this criteria and list all the datasets that they want to be duplicated on DD. Once we receive feedback from all PWGs and decide on a priority list, we will discuss with the S&C team to see which datasets can be actually duplicated due to the capacity of the DD.

- What is the current progress of BES-II embedding?
- A postdoc from BNL/KSU is leading the efforts to understand the issue and tune TpcRS. Currently, the discrepancy between data and embedding seems to originate from different TPC cluster finders used. Further investigations are ongoing.
